Hello, so last month (january) i had unprotected sex (my partner didn’t ejaculate at all) and got my period 3 weeks later when it was due, maybe 1 day late or so. I am positive it was my period and not the bleeding associated with pregnancy because it lasted for 5-6 days, as my normal periods usually last for, and it was quite heavy and bright red the first days with horrible cramps; nothing new for my periods. However, this month I am 3 days late. I do feel some PMS (light cramping and back pains) but that’s about it. I know it sounds impossible to be pregnant but still, is it a slight chance that I am?
